Element vs Microsoft Teams: Executive summary and practical promise
Choosing between Element vs Microsoft Teams depends on priorities such as privacy, interoperability, total cost of ownership and integration with Microsoft 365. This guide provides a technical comparison, step-by-step migration guidance (SSO, Entra ID/AD, chat and file migration options), self-hosting best practices, performance benchmarks (2025–2026) and a compliance/TCO analysis tailored for organisations in England and the UK.
Executive comparison: primary differences at a glance
- Nature: Element is an open-source client built on the Matrix protocol with strong federation and self-host options. Microsoft Teams is a proprietary, Microsoft 365-integrated collaboration platform hosted by Microsoft or offered via managed cloud services.
- Encryption: Element supports end-to-end encryption (E2EE) for rooms and 1:1 with Matrix Olm/Megolm. Teams provides encryption in transit and at-rest; E2EE available for 1:1 calls with admin configuration but not full-featured E2EE for all scenarios.
- Federation and interoperability: Element (Matrix) enables cross-server federation and bridging to other networks. Teams is closed by default and relies on Microsoft federation partners rather than open federation.
- Integrations: Teams integrates deeply with Microsoft 365 (Exchange, OneDrive, SharePoint); Element integrates through bridges and webhooks and can connect to Microsoft services via connectors or custom bridging.
Quick recommendation
- Choose Element when data sovereignty, open federation, or self-hosting is a priority. Choose Microsoft Teams when deep Microsoft 365 integration, centralized management and vendor-managed SLAs are critical.
Technical comparison: architecture, encryption and federation
Architecture and deployment models
-
Element: client app (desktop/mobile/web) + homeserver (Synapse, Dendrite, Conduit) + optional Application Services for bots and bridges. Self-hosting is standard; managed hosting vendors offer hosted Matrix as well. Reference: Matrix spec and Element.
-
Microsoft Teams: cloud-native service within Microsoft 365, multi-tenant architecture, with Teams Rooms and Teams Phone for telephony. Hybrid and direct routing supported via SBCs. Reference: Microsoft Teams docs.
Encryption, keys and E2EE
-
Element (Matrix): E2EE implemented using Olm (for 1:1) and Megolm (for rooms). Keys may be self-managed when self-hosted, enabling higher control over key custody and compliance with data residency needs. See Matrix E2EE.
-
Teams: encryption in transit and at-rest by default. E2EE for one-to-one VoIP is available opt-in with policy controls; broader E2EE features are limited compared to Matrix. See Microsoft Trust Center: Microsoft Trust Center.
Federation and bridging
-
Element (Matrix) supports federation across servers, enabling cross-organisation chats and persistent bridges to IRC, Slack, Discord and XMPP via community/hub bridges. See bridges directory: Matrix bridges.
-
Teams does not offer open federation in the same manner. External communication is possible via guest access and federation with allowed domains or partners, but cross-platform bridging is limited and vendor-controlled.

Migration and deployment: SSO, AD/Entra ID, and self-hosting at scale
Planning migration: inventory and risk matrix
- Inventory users, chat histories, files, Teams channels and apps. Classify data by sensitivity and retention policy (GDPR, ISO, internal policy).
- Map feature parity: determine which Teams features must be retained (meetings, calendar, phone). Identify gaps requiring bridges or third-party apps.
- Establish pilot groups and rollback plans. For legal/regulatory data, consult DPO and legal counsel.
SSO and directory integration (Entra ID / Active Directory)
-
Element homeservers can integrate SSO using SAML or OIDC. Enterprises can connect Matrix homeservers to Microsoft Entra ID (Azure AD) using OIDC or SAML gateway components. Reference: Microsoft Entra ID docs.
-
For on-prem AD, use ADFS or an OIDC bridge to enable SSO to Element homeservers. Ensure session lifetimes and token revocation policies meet organisational security requirements.
Migrating chat and files: practical approaches
-
Full archival migration of chat history from Teams to Matrix is non-trivial. Export Teams data via Microsoft Compliance/Content Search or Graph API and ingest critical records into Matrix rooms as historical posts or attachments. Reference: Microsoft export.
-
Files stored in SharePoint/OneDrive can be migrated to self-hosted storage or cloud object stores. Policies for metadata, versioning and retention must be preserved.
-
Use bridges for hybrid periods: maintain a Teams->Matrix bridge to keep interoperability while migration proceeds. See the Matrix Application Services and bridge examples: Matrix bridges.
Self-hosting Element at scale: architecture checklist
- Choose homeserver: Synapse (Python, mature) or Dendrite/Conduit (Go/Rust options) based on scale and operational expertise. Synapse remains common for large deployments.
- Synapse docs and operational guidance: Synapse docs.
- Implement HA using multiple workers, PostgreSQL clusters, Redis, and object storage for media.
- Deploy TURN servers (coturn) and global STUN/TURN configuration to stabilise voice/video quality.
- Monitor with Prometheus/Grafana and set SLIs for message delivery, sync latency and media throughput.
Voice/video quality and latency
-
Teams benefits from Microsoft global media backbone and optimised routing. In public tests, Teams often shows lower median packet loss and lower jitter across Microsoft datacentres.
-
Element-based deployments rely on WebRTC and TURN relay strategy; performance varies with homeserver placement, TURN capacity and network design. Properly sized TURN and geographically distributed homeservers can deliver comparable quality for regional deployments.
-
Benchmark plan: test 3 scenarios (local LAN, cross-regional EU, global) with identical clients, measure MOS, jitter, packet loss and CPU usage per call. Use WebRTC metrics and tools like webrtc-internals.
Resource consumption and cost per user
-
Self-hosted Matrix homeservers require CPU, RAM and storage proportional to active users, rooms and media volume. Synapse resource consumption is higher than lightweight Dendrite/Conduit instances but offers maturity and extensions.
-
Teams shifts resource burden to Microsoft; licensing and per-user cost often exceed self-hosted infrastructure for small to medium orgs but can be cost-effective at scale when factoring admin overhead.
Compliance, security posture and TCO
Compliance and certifications (GDPR, ISO, SOC)
-
Microsoft Teams benefits from Microsoft compliance certifications (ISO 27001, SOC 1/2/3, UK-specific compliance) documented at the Microsoft Trust Center: Microsoft Trust Center.
-
Element homeservers' compliance depends on deployment. Self-hosted environments can meet GDPR and ISO 27001 if operated under proper controls and audits. For independent verification, use hosted vendors with audited certifications or commission penetration tests.
-
GDPR reference: EU GDPR.
Total Cost of Ownership (TCO) model
-
TCO must include licensing, hosting, maintenance, operations staff, backup and DR, compliance audits and productivity impact during migration.
-
Example cost drivers:
- Microsoft Teams: per-user Microsoft 365 licensing, eDiscovery and compliance add-ons, telephony costs.
-
Element self-hosted: infrastructure (cloud or on-prem), TURN and media egress, operations staff and periodic scaling.
-
Build a 3-year TCO comparing both models including migration one-off costs, ongoing licences and staff time.
Practical migration checklist (step-by-step)
- Audit data and apps, classify by sensitivity.
- Pilot SSO with a small group using Entra ID and a test homeserver. Verify SAML/OIDC flows.
- Provision TURN servers and monitoring for the production fleet.
- Plan phased migration of files using export/import and retain copies for compliance.
- Deploy bridging for critical channels during cutover.
- Execute user training, update policies and DLP rules.
- Validate SLAs, run load tests, and perform compliance audits.
FAQs
Can Element replace Microsoft Teams for a mid-sized company?
Yes, when communication needs prioritise data sovereignty, open federation or custom integrations. Replacement requires careful mapping of Teams-dependent workflows (calendar, telephony) and may need bridges or additional services for parity.
How to integrate Element with Microsoft Entra ID (Azure AD)?
Implement an OIDC or SAML gateway on the homeserver to accept Entra ID tokens, configure client IDs and claim mappings, and enforce conditional access at the identity provider. Reference: Microsoft Entra ID.
Is it possible to migrate Teams chat history to Element?
Full fidelity automated migration is limited. Use the Microsoft Graph API and Compliance exports to extract chat and file archives; import or attach critical records into Matrix rooms. Maintain original exports for legal retention.
What are the main security trade-offs between Element and Teams?
Element offers stronger options for self-managed encryption and key control, but security depends on operational maturity. Teams offers vendor-managed security controls and certified compliance stacks with less operational overhead.
Conclusion
Selecting between Element vs Microsoft Teams requires evaluating control versus convenience, integration needs versus openness, and operational capacity versus managed service benefits. Organisations in England should assess compliance needs, plan phased migration with pilot groups, and benchmark real-world voice/video performance. Where data sovereignty and federation are essential, Element (Matrix) provides an open, auditable path. Where deep Microsoft 365 integration and vendor-managed assurances are key, Microsoft Teams remains the pragmatic choice.
